Free CAD Library

This is a FREE collection of CAD builder files. These files do not give away any proprietary information, but allow for builders to accurately model parts that otherwise would be extremely difficult to measure and create models for.

If you would like to donate files to the library, reach out through our "Contact Us" page and we would love to add them to the library. We request that only files that are currently free on the internet, or that have been created by you be submitted. Files currently for sale on the internet will not be accepted. Thank you!
